There are many thyroid problems. In the case of hyperthyroidism, symptoms such as panic and excessive sweating may occur; in the case of hypothyroidism, there may be fatigue, hair loss, and elevated blood lipids; in the case of subclinical hyperthyroidism and hypothyroidism, the symptoms may be mild; and in the case of simple thyroid nodules, there are usually no symptoms if there is no pressure on the thyroid gland. There are many kinds of thyroid diseases, such as hyperthyroidism, hypothyroidism, subclinical hyperthyroidism and hypothyroidism, and simple thyroid nodules. The early symptoms of different diseases are different. 1. Early hyperthyroidism patients usually have symptoms such as panic, hand tremors, excessive sweating, tachycardia, irritability and weight loss. 2. Hypothyroidism patients have the opposite symptoms of hyperthyroidism patients, such as fatigue, indifference, slow heart rate, hair loss and elevated blood lipids. 3. Symptoms of subclinical hyperthyroidism and hypothyroidism are less severe than those of hyperthyroidism and hypothyroidism, or no symptoms are shown. 4. Simple thyroid nodules without compression in the early stage usually have no obvious early symptoms. If you suspect that your thyroid gland is abnormal or if you experience any of the above symptoms, it is recommended that you go to the hospital in a timely manner.
